6. Pin Descriptions
In order to reduce pin count, and therefore size and cost, some pins have multiple functions. In such cases,
the functions are separated with a ‘/’ symbol. Refer to the Pin Assignments diagram on page 4 for a
graphical representation.
The following signal type codes are used in the tables:
I: Input.
O: Output
T/S: Tri-State bi-directional input/output pin.
S/T/S: Sustained Tri-State.
O/D: Open Drain.
